Title (EN) OIL-IN-WATER-TYPE EMULSION COSMETIC
(FR) PRODUIT COSMÉTIQUE DE TYPE ÉMULSION HUILE DANS EAU
(JA) 水中油型乳化化粧料
Abstract:
(EN) The present invention addresses the problem of providing an oil-in-water-type emulsion cosmetic which contains an ultraviolet ray scattering agent and of which the preparation stability in a system where a water-soluble alkyl-substituted polysaccharide derivative and another emulsifying agent coexist is further improved. The present invention relates to an oil-in-water-type emulsion cosmetic characterized by containing (A) a water-soluble alkyl-substituted polysaccharide derivative, (B) a nonionic surfactant and (C) an ultraviolet ray scattering agent, wherein the blend ratio [(A)/(B)] of the water-soluble alkyl-substituted polysaccharide derivative (A) to the nonionic surfactant (B) is 1.54 or less, and the blend ratio [(A)/(C)] of the water-soluble alkyl-substituted polysaccharide derivative (A) to the ultraviolet ray scattering agent (C) is 0.02 or less.
(FR) La présente invention cherche à résoudre le problème qui est de fournir un produit cosmétique de type émulsion huile dans eau qui contienne un agent de diffusion du rayonnement ultraviolet et permette d'encore améliorer la stabilité de la préparation dans un système où coexistent un dérivé de polysaccharide substitué par un alkyle hydrosoluble et un autre agent émulsifiant. La présente invention concerne un produit cosmétique de type émulsion huile dans eau caractérisé en ce qu'il contient (A) un dérivé de polysaccharide substitué par un alkyle hydrosoluble, (B) un tensioactif non ionique et (C) un agent de diffusion du rayonnement ultraviolet, le rapport de mélange [(A)/(B)] du dérivé de polysaccharide substitué par un alkyle hydrosoluble (A) au tensioactif non ionique (B) étant de 1,54 ou moins, et le rapport de mélange [(A)/(C)] du dérivé de polysaccharide substitué par un alkyle hydrosoluble (A) à l'agent de diffusion de rayonnement ultraviolet (C) étant de 0,02 ou moins.
(JA) 紫外線散乱剤を含み、さらに水溶性アルキル置換多糖誘導体と他の乳化剤とが共存する系において、製剤の安定性を更に向上させた水中油型乳化化粧料を提供することを目的とする。本発明は、(A)水溶性アルキル置換多糖誘導体;(B)非イオン性界面活性剤;及び(C)紫外線散乱剤を含有し、前記(A)水溶性アルキル置換多糖誘導体と(B)非イオン性界面活性剤の配合量比率[(A)/(B)]が1.54以下であり、かつ前記(A)水溶性アルキル置換多糖誘導体と(C)紫外線散乱剤の配合量比率[(A)/(C)]が0.02以下であることを特徴とする水中油型乳化化粧料に関する。
